ZYD series outside lubrication gear oil pump

Structure& Operation Theory

Working Principle

Driving gear (outside rotor) with internal tooth drives the internal rotor and turns in same direction in the full closed pump body. The inlet is from the outlet. When it turns, negative pressure formed at the suction port, the liquid inlet and being take to the outlet by rotor, then the liquid is impelled from the discharge port and the gears mesh. The transportation of liquid finished.

Structure Feature

As figure, the pumps are mainly composed of internal rotor, outside rotor, shaft, pump casing, front cover, seal, bearing etc.

The pump' seal adopts packing seal or mechanical seal. When the delivered medium is high temperature, high viscosity or strong corrosion, packing seal should be adopted.

When the delivered medium is easy crystal linic, we can design the heat preservation jacket in pump casing and front cover in order to melt the medium with steam when working. The pump can be also fitted with the safety valve.

The pump set is composed of the pump, motor and baseplate.

The driving way is belt wheel driving or coupling driving.

Package& Transportation

Application Scope

ZYD outside lubrication pump compared with common pump, without lubrication or poor lubricity in transmission or liquid containing fine particles, there are a lot of strong practicality, is a typical soap liquid pump.

Application 

1. It can give performance as transfer pump or booster in oil deliver system.

2. It can be also applied as fuel pump for delivery system, pressurization and injection in fuel supply system.

3. It can be also hydraulic pump supplying hydraulic power in hydraulic system;

4. In all industry fields it can be as lubricating pump.

Structure Features

ZYD outside lubrication pump adopts the structure of the bearing and transmission medium phase segregation, separate lubrication of the bearing, gear made of alloy cast steel and special heat treatment process, the gear surface hardness can reach above HRC60, have extremely strong wear resistance, thus greatly improving the pump alternative life.
